Help needed urgently...(thread title lost)

I'm a WII newbie( Though i bought it for about 2 year) but, about few months before, I wanted to go Internet, So i go for Option, once i click the setting tab, it goes OPERA ERROR! , i tried to find a solution for this error, but for solution, Yes. FYI, i have NO homebrew channel ( Just wanted to install ) , NO Hackmii. And recently , worst. I was playing Super Smash Bros. Brawl then 1 day i gone to thailand and bought a game there named Pikachu's Adventure. After I came back to my hometown(Malaysia) i try out the game, And it auto update firmware, after i updated the firmware, i found out i cant even play my Super Smash Bros Brawl and Final Fantasy fables :Chocobo's Dungeon.
*My wii default language is Japanese, so i think it's a PAL.
**the game(SSBB,FinalFantasy) i played is all in English language.
***I DONT HAVE the HomeBrew channel and Hackmii (Just wanted to install)

Erm..I mean, You see, i now also quite NOT understand about what talking in that guide, i just tried to follow very hard coz i am a newbie. i wanted to ask the thread too, but as u see, that's a past year post....
